GAS-BURNER.

Specification of Letters Patent.

Patented Dec. d, 191'?.

Application filed August 26, 1916. Serial No. 117,019.

To all whom t may concern.'

Be it known that I, JAMES B. SLATTERY, a citizen of the United States,and resident of Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Gas-Burners, ofwhich the following is a specification.

This invention relates to gas burners and especially to that class wherea row of jets or a continuous flame of some length is burned and thedevice consists of a mixing chamber having in one side a slot for theeXit of the gas to be burned and at an elevation from the mixing chamberto prevent back flash and at the same time to provide means for soadjusting the slot as to provide for the thickness of the flame, as willbe more fully described in the following specification, set forth in theclaims and illustrated in the accompanying drawings, wherein:

Figure 1 is a side view of the improved burner.

Fig. 2 is an enlarged view of the outer end of the burner partly insection.

Fig. 3 is a cross sectional view of the same.

Fig. 4 is a view similar to Fig. 2 but of a modified form of burner.

Fig. 5 is a cross sectional view of the latter.

In gas burners for the various types of heaters it is essential that theame be one of maximum area and minimum volume, and heretofore a seriesof jets have been used and which are formed by minute perforations inone side of a pipe. The serious objection to this class of burners hasbeen the liability of the flame to back flash and light the flame at theinclosed end ofthe blast pipe. This danger may be reduced in many casesby the use of wire gauze between the blast pipe and the outletperforations, but the gas pressure is consequently reduced and the iiameis lessened.

The present invention consists of the usual mixing chamber 10 preferablymade of sheet steel and having heads 11 with ears 12 to secure theburner to any desired support. 'Ihe burner may be carried, however, bythe elbow 13 of the air chamber 14 at the end of the gas pipe 15. j j

The chamber 10 is cylindrical and is open along its upper side. It ispreferably made of sheet steel for resiliency and lightness and theopening 16 is formed by two substantially vertical walls 17 turnedbackward on themselves to form a double thickness and make them rigidand they are of such distance apart at their upper ends to permit of theescape of the mixed gas throu jh an opening 18 which is a slot alongpractically the whole length of the burner.

In order to maintain the proper width for this slot or opening 18 rivets19 are passed through both walls 17 and the proper width thus retained.

I/Vhen it may be necessary to burn two or more gases or vapors atdifferent times in this device it will be desirable to adjust the outlet18 and this is done by dispensing with the rivets and using bolts 2Owhose nuts 21 may be adjusted and the opening reduced or enlarged as maybe desired.

While the permanent burner has its end provided with a metallic fillingpiece 22 held in Vplace by one of the rivets 19, the adjustable burnermay have at its ends and above the heads 11 flexible filling pieces 23such as asbestos, which will yield or com- ,press as the opening isaffected.

To permit of the proper adjustment of the slot or opening 18 thecylinder 10 and the upright walls are made of the thin resilientmaterial to spring apart when the bolts are loosened or yield when theopening is reduced. The heads 11 may be secured within the cylinder byany well known means.

It is obvious that the device may be otherwise arranged or modifiedwithout departinclined toward each other at their upper and adjustingscrews connecting the lips to edges, and means for adjusting theinclinacause them to approach or retract at their tion of the lips. lupper edges. 10
